The various packaging methods of soft pack batteries and the advantages of
soft pack lithium batteries.
1、 What is a soft pack lithium battery
(1) When it comes to soft pack batteries, many application scenarios should come to mind. They are not unfamiliar in our daily lives. In addition to power lithium batteries, power batteries are the most common battery components in 3C electronic devices. For example, the internal rechargeable battery on a mobile phone is integrated and cannot be disassembled without authorization.
(2) Soft pack rechargeable battery: Refers to soft pack batteries, the key difference depends on the different packaging materials of the lithium motor casing, which is the use of aluminum-plastic composite film (commonly known as aluminum-plastic film). Other lithium batteries are similar to positive, negative, lithium battery electrolytes, separators, and other lithium battery materials.
2、 Lithium battery packaging method
(1) The overall packaging of lithium battery casings can be divided into: first generation, steel casing; Second generation, aluminum shell; Third generation, soft pack aluminum-plastic film.
(2) The significant damage caused by rechargeable lithium batteries is due to the potential instability of lithium battery materials and other unexpected factors, which can lead to uncontrolled heat generation and result in invisible vapor deposition within the rechargeable battery. The steel or aluminum casing creates a fixed and immovable space, limiting the expansion of the vapor and causing explosions in rechargeable batteries. In that way, the soft pack packaging of batteries emerged in response to the times.. Soft pack packaging for batteries, commonly used aluminum-plastic film is too soft, resulting in physical deformation. Once there is a safety risk, at most it is a burst of air.
3、 The advantages of soft pack lithium batteries
Except for soft pack
lithium batteries, relative safety. Compared with steel shells, lithium batteries can also save net weight, volume, and reduce internal resistance. In that way, improving the relative density quality or bulk density of lithium batteries would be of great benefit. In addition, soft pack batteries also have the characteristics of low cycle system wear and tear, and diverse packaging designs.
